High productivity, precise tolerances, and immaculate surface finishes have become non-negotiable standards in today’s industrial manufacturing.Ejector pins play a key role by releasing parts from molds or dies, but traditional mechanical pins can leave marks or damage delicate parts. That’s why many manufacturers now turn to air ejector pins, which use controlled air pressure to gently and precisely eject finished products. These innovative pins provide cleaner, faster, and more reliable ejection, supporting the quality and efficiency demands of modern production. In this article, we’ll look at what air ejector pins are, how they work, their benefits over traditional systems, and tips for keeping them performing at their best.
View MorePrecision and efficiency are essential in today’s plastic injection molding industry to stay competitive and meet high-quality standards. A vital element in this process is the ejector pin system, which safely and effectively releases finished parts from molds. While traditional mechanical ejector pins have been reliable for decades, the increasing complexity of product designs and stricter surface quality requirements have exposed their limitations. Customized air ejector pins offer a modern, tailored solution that enhances product quality, minimizes defects, and boosts overall molding efficiency.

When selecting materials for these pins, SUS420 stainless steel has become a preferred option due to its excellent combination of strength, corrosion resistance, and wear durability. This makes SUS420 especially well-suited for ejector pins that operate in demanding manufacturing environments where high precision and long service life are essential. Its superior hardness ensures that the pins maintain tight tolerances even after extended use, while its resistance to corrosion helps prevent degradation caused by exposure to moisture and chemicals.
